Abstract
A method of producing a superconducting wire including A-B-C-D system oxide superconductor wherein A is an at least one element of group IIIa of the Periodic Table, B is an at least one alkali earth metal, C includes Cu and D includes O. In the method, a material containing at least one of both A and B is arranged inside or outside an elongated tubular coating layer, which includes a copper alloy and at least the other one, to form a composite element. Then, the composite element undergoes a heat treatment to produce the superconductor.
